Excellent problem description
Problem description, pseudo code, and overall document well organized and easy to read
Typo on tests section? "...for indexes on read1, read2..." should be "indexes on index1, index2..." ?
Clear description of output, meets assignment criteria

I think storing the information in two dictionaries and then comparing those is more computationally intensive than it needs to be. You could could read all four files and then compare the records from all four files directly. But your overall process accomplishes what needs to be accomplished.
